14. The method for using a crossbow cocking system of claim 13, further comprising

eitheroperationally engaging each tab of the first plurality of tabs with a tab cavity, and

operationally disengaging each tab of the first plurality of tabs from a tab cavity, and

operationally engaging each tab of the second plurality of tabs with a tab cavity;

or

2) operationally engaging each tab of the second plurality of tabs with a tab cavity, and

operationally disengaging each tab of the second plurality of tabs from a tab cavity, and

operationally engaging each tab of the first plurality of tabs with a tab cavity.

15. A crossbow comprising
